Using the SharePoint Online Sensitive by Default Control

Sensitive by Default for SharePoint Online.

The Sensitive by Default control allows tenants to prevent external access to newly uploaded documents until DLP processing checks their content.

You can combine the sensitive by default control with sensitivity labels to exert maximum control over confidential material.

Microsoft 365 Data Loss Prevention and Encrypted Message Type Exceptions

Microsoft 365 Data Loss Prevention (DLP) policies have wide-ranging capabilities when it comes to rules and exceptions. One exception covers the various types of encrypted email that can pass through the Exchange Online transport pipeline. As it happens, three message types are supported, but who could have guessed that permission controlled means rights management?

Microsoft 365 DLP Switches from Envelope to Header for Sender Evaluations

To make Microsoft 365 DLP policies work like Exchange transport-rule based DLP, a January change will switch evaluation of sender conditions away from envelope information to message headers. Although this change might seem to be something beloved of email geeks, it’s actually an important update for organizations who want to move away from ETR-based DLP to Microsoft 365 DLP policies.

How to Create a DLP Policy to Stop External Sharing of Teams Meeting Recordings

Microsoft Overselling E5 Capabilities Through Data Loss Prevention

Microsoft plans to surface recommendations to use communications compliance policies as part of its DLP workflow. That sounds acceptable, but it’s the second example of how Microsoft pushes high-priced premium features to Office 365 tenants through DLP. Apart from the undesirability of pushing features to customers through software, communications compliance is not something that you implement on a whim, so why does Microsoft think this is a good idea?

Use Distribution Lists or Security Groups to Add Accounts to DLP Policies

Teams Data Loss Prevention (DLP) policies help to stop users sharing confidential information through chats and channel conversations. A recent update means that accounts to be included or excluded in DLP policies can be specified using distribution lists or mail-enabled security groups.

Microsoft Releases New Sensitive Information Types

Microsoft has released a set of new sensitive information types, used to locate sensitive data by Microsoft 365 DLP policies.

How to Use DLP Policies and Sensitivity Labels to Block External Access to Confidential Documents

When you need to block external access to your most sensitive documents, Office 365 Data Loss Prevention policies and sensitivity labels combine to find and protect the documents. A really simple policy is enough to detect and block external access, and is covered by Office 365 E3 licenses. If you have E5 licenses, you can consider auto-label policies to find and protect sensitive documents at scale.

How to Apply Encryption to Exchange Online Email Containing Sensitive Data

Office 365 offers different ways to apply encryption to important messages. When those messages hold sensitive data known to Office 365, like credit cards or passport numbers, we can define a transport rule or DLP policy to protect outbound email automatically. And while you can define rules and policies through the GUI, PowerShell is available too.
